Biomarkers of Waterpipe Tobacco Smoke Exposure: A Systematic Review and Meta-Analysis.

INTRODUCTION: The prevalence of waterpipe tobacco smoking is increasing globally. Biomarkers of waterpipe tobacco smoke (WTS) exposure are less studied. AIMS AND METHODS: To identify the types of biomarkers of WTS exposure and estimate changes in biomarker concentrations pre- to post-WTS exposure. PubMed, Embase, Web of Science, CINAHL Plus, PsycINFO, and Cochrane Library were searched for studies up to April 24, 2023. The types of biomarkers were identified. Random-effects models were used to estimate changes in biomarker concentrations pre- to post-WTS exposure. RESULTS: Seventy-three studies involving 3755 participants exposed to WTS (49% male, mean age: 24.8 years) and 11 types of biomarkers of WTS exposure were identified. The biomarkers included tobacco alkaloids, expired carbon monoxide (eCO), carboxyhemoglobin (COHb), tobacco-specific nitrosamines, volatile organic compounds (VOCs), polycyclic aromatic hydrocarbons (PAHs), heavy metals, unmetabolized VOCs, unmetabolized PAHs, furan metabolites, and heterocyclic aromatic amines. Compared with pre-WTS exposure, eCO (breath; mean difference [MD] 27.00 ppm; 95% confidence interval [CI]: 20.91 to 33.08), COHb (blood; MD 4.30%; 95%CI: 2.57 to 6.03), COHb (breath; MD 7.14%; 95%CI: 4.96 to 9.31), nicotine (blood; MD 8.23 ng/mL; 95%CI: 6.27 to 10.19), and cotinine (urine; MD 110.40 ng/mL; 95%CI: 46.26 to 174.54) significantly increased post-WTS exposure. CONCLUSIONS: Biomarkers of WTS exposure were systematically identified. The similarity between the biomarkers of WTS exposure and those of cigarette smoke and higher concentrations of some biomarkers post-WTS exposure underscore the need for further research on applying biomarkers in surveillance, interventions, and regulations to mitigate the harms of waterpipe tobacco smoking. IMPLICATIONS: This study provides the first comprehensive overview of biomarkers investigated and available for assessing WTS exposure and their concentration changes in the human body. Researchers can use biomarkers such as eCO, COHb, nicotine, and cotinine to measure the health risks associated with WTS exposure and objectively evaluate the effectiveness of public health interventions aimed at reducing waterpipe tobacco smoking. Public health policymaking can also be informed through increased biomarker concentrations following WTS exposure, to implement regulations and public health education campaigns on limiting or preventing waterpipe tobacco smoking.

Prevalence and assessment tools of cancer-related cognitive impairment in lung cancer survivors: a systematic review and proportional meta-analysis.

PURPOSE: Cancer-related cognitive impairment (CRCI) is a significant risk factor influencing the quality of life in lung cancer survivors. No absolute assessment tool has been confirmed to assess CRCI in lung cancer survivors. This review was undertaken to pool the overall prevalence of CRCI and to summarize the assessment tools in assessing CRCI among lung cancer survivors. METHODS: PubMed, Cochrane Library, Embase, CINAHL, and CNKI were searched to retrieve articles reported CRCI prevalence. Summary prevalence estimates were pooled using a random effects model, along with corresponding 95% prediction intervals (PIs). The Freeman-Tukey double arcsine transformation of proportions was incorporated in the analysis. Additionally, subgroup analysis, meta-regression, and leave-one-out analysis were performed. RESULTS: A total of 12 studies, involving 1934 survivors, were included in the review. All of these studies were found to have a low risk of bias in terms of their methodological quality. Four studies (33.3%) utilized the International Cognition and Cancer Task Force (ICCTF) criteria to identify CRCI through neuropsychological tests. The pooled prevalence rate of CRCI was found to be 26% (95% PI, 16-37%), I2 = 95.97%. The region in which the studies were conducted was identified as a significant factor contributing to this heterogeneity (p = 0.013). No indication of small-study effects was found (Egger's test: p = 0.9191). CONCLUSION: This review provides an overview of CRCI prevalence and assessment tools in lung cancer survivors. The findings can serve as epidemiological evidence to enhance clinicians' and researchers' understanding of early detection and assessment.

Navigating tensions when life-sustaining treatment is withdrawn: A thematic synthesis of nurses' and physicians' experiences.

AIM: To synthesise nurses' and physicians' experiences with withdrawing life-sustaining treatment in an intensive care unit. DESIGN: The chosen methodology is thematic synthesis. The Preferred Reporting Items for Systematic Review and Meta-Analyses and Enhancing Transparency are used in Reporting the Synthesis of Qualitative Research Statement. METHODS AND DATA SOURCES: A systematic search is conducted in APA PsycINFO, CINAHL Plus, EMBASE, PubMed and Web of Science following the inclusion and exclusion criteria in April 2023. Two reviewers independently screened and extracted the qualitative data. Subsequently, data analysis was conducted using thematic analysis of qualitative research. This study was not registered with any review registry due to the irrelevance of the data to health-related outcomes. RESULTS: From the 16 articles, 267 quotes were extracted and analysed. The findings of the study revealed five analytical themes: (1) tensions between interdependent collaboration and hierarchical roles; (2) tensions between dignified dying or therapeutic perspectives; (3) family members' reflections of patient's wishes; (4) tensions in family members' positions; and (5) double-sidedness of distress. CONCLUSION: This study contributes to nursing knowledge by providing a more nuanced understanding of this complex phenomenon of withdrawing life-sustaining treatment. The findings of this study have revealed significant variations globally in the practices surrounding the withdrawal of life-sustaining treatment in intensive care units, emphasising the need for further research to inform clinical practices that cater to diverse contexts. REPORTING METHOD: Enhancing Transparency are used in Reporting the Synthesis of Qualitative Research Statement (ENTREQ statement). PATIENT OR PUBLIC CONTRIBUTION: Since this study reported a potential collision between the patient's dignified dying and the family member's perceptions and interests, the family member's wishes should be carefully distinguished from the patient's quality of end of life in practice.

Effects of Different Exercises on Physical Function, Dialysis Adequacy, and Health-Related Quality of Life in Maintenance Hemodialysis Patients: A Systematic Review and Network Meta-Analysis.

BACKGROUND: Clinical guidelines recommend exercise training for patients undergoing maintenance hemodialysis (MHD). However, the effectiveness of different types of exercise remains uncertain. OBJECTIVES: The aims of the study were to compare and rank the effect of different types of exercise on walking capacity, cardiorespiratory fitness, dialysis adequacy, and health-related quality of life (HRQOL) in patients undergoing MHD. METHODS: Eight databases (four English and four Chinese) were searched from inception to January 1, 2022. Randomized controlled trials evaluating the efficacy of different exercises for patients undergoing MHD were included. Two independent reviewers screened the literature, extracted data, assessed the risk of bias, and evaluated the certainty of evidence. A frequentist random-effect network meta-analysis was conducted. RESULTS: Ninety trials with 4,084 participants comparing 15 types of exercise were included, reporting on the six-minute walking test (45 trials), peak oxygen uptake (22 trials), dialysis adequacy (30 trials), and HRQOL (23 trials). Network meta-analysis showed that the most effective intervention for walking capacity was intradialytic aerobic exercise combined with blood flow restriction with a mean difference and 95% confidence interval of 97.35 (11.89-182.81), for peak oxygen uptake it was non-intradialytic combined aerobic and resistance exercise with a value of 4.35 (2.25-6.44), for dialysis adequacy it was intradialytic combined aerobic and resistance exercise with a value of 0.17 (0.06-0.28), for the physical component summary of HRQOL it was intradialytic aerobic exercise with a value of 4.93 (2.31-7.54), and for the mental component summary of HRQOL it was non-intradialytic combined aerobic and resistance exercise with a value of 6.36 (0.45-12.27). Ultimately, intradialytic combined aerobic and resistance exercise could improve all the above outcomes compared to usual care. CONCLUSIONS: This study concluded that intradialytic combined aerobic and resistance exercise is optimal for MHD patients due to its significant positive effects on multiple outcomes. Walking capacity can be further enhanced by combining blood flow restriction with exercise. For improving dialysis adequacy, intradialytic exercise proves to be more effective than non-intradialytic exercise. Further well-designed clinical trials are needed to investigate the effects of exercise with varying durations, intensities, and frequencies.

Postoperative recovery among head and neck cancer patients receiving microvascular free flap surgery with implementing nurse-protocolized targeted sedation: relationship of use of sedatives and mechanical ventilation to length of ICU stay.

PURPOSE: Patients receiving microvascular free flap surgery are usually admitted to a high-dependency adult intensive care unit (ICU). Research is limited to investigate postoperative recovery among head and neck cancer patients in the ICU. This study aimed to evaluate a nursing-protocolized targeted sedation on postoperative recovery and to examine the relationship of demographic characteristics, use of sedation, mechanical ventilator to length of ICU stay in patients receiving microvascular free flap surgery for head and neck reconstruction. METHODS: This retrospective study involves 125 ICU patients at a medical centre in Taiwan. Medical records were reviewed between 1 January 2015 and 31 December 2018 including surgery-related data, medications and sedations used, and ICU-related outcomes. RESULTS: The mean length of ICU stay was 6.2 days (SD = 2.6), and the mean duration of mechanical ventilation was 4.7 days (SD = 2.3). The daily dosage of sedation used in patients who received microvascular free flap surgery was dramatically reduced since the postoperative day (POD) 7. Over 50% of patients switched to PS + SIMV ventilator mode on POD 4. Duration of sedation used (r = 0.331, p < 0.001), total dosage of sedation (r = 0.901, p < 0.001), clear consciousness (r = - 0.517, p < 0.001), and duration on mechanical ventilator (r = 0.378, p < 0.001) are correlated with the length of ICU stay. CONCLUSION: This study provides an understanding of the use of sedation, mechanical ventilator, and length of ICU stay to inform the continued education for clinicians.

Constructing the concept of healthy ageing and examining its association with loneliness in older adults.

BACKGROUND: World Health Organization (WHO) has defined healthy ageing by highlighting five functional ability domains to (meet basic needs, make decisions, be mobile, build and maintain relationships, and contribute to society), which also emphasized the importance of addressing loneliness as priorities within United Nations Decade of Healthy Ageing initiative. However, the level and determinants of healthy ageing and its association with loneliness are rarely examined. This study aimed to construct a healthy ageing index to verify the WHO healthy ageing framework, measure five domains of functional ability of older adults and examine the relationship between functional ability domains and loneliness. METHODS: A total of 10,746 older adults from the 2018 China Health and Retirement Longitudinal Study (CHARLS) were included. A healthy ageing index ranging from 0 to 17 was constructed using 17 components related to functional ability domains. Univariate and multivariate logistic regression analyses were utilized to determine the association between loneliness and healthy ageing. The STROBE guidelines with the RECORD statement for observational studies using routinely collected health data were observed. RESULTS: The factor analysis verified the five functional ability domains for healthy ageing. After adjusting for confounders, being mobile, building and maintaining relationships, and learning, growing and making decisions were significantly associated with lesser loneliness among participants. CONCLUSIONS: The healthy ageing index of this study can be utilized and further modified with respect to large-scale research with relevant healthy ageing topics. Our findings will support healthcare professionals to provide patient-centered care when identifying their comprehensive abilities and needs.

Associations between older adults' social media use behaviors and psychosocial well-being.

BACKGROUND: Research examining associations between social media use behaviors and psychosocial well-being among older adults are limited. AIMS: To explore associations between older adults' social media (social networking services and instant messaging applications) use behaviors and psychosocial well-being. METHODS: This was a secondary data analysis. All data were retrieved from the Taiwan Communication Survey database, an annual survey that examines trends in Taiwanese residents' communication behaviors and social media use. The original investigation was conducted in Taiwan from September to December 2019. Data from 647 older adults aged over 60 years were extracted for the analyses. Social media use behaviors (users/non-users and time spent using), positive psychosocial outcomes (life satisfaction, self-determination, subjective well-being, and happiness), negative psychosocial outcomes (loneliness, depression, and anxiety), and demographic variables were included. RESULTS: Social media users had significantly higher levels of subjective well-being and lower levels of depression, anxiety, and loneliness compared with non-users. Time spent on social networking services was significantly and positively correlated with negative psychosocial outcomes (ß = 0.103, p = 0.044, f2 = 0.011), and it was significantly and inversely correlated with positive psychosocial outcomes (ß = - 0.063, p = 0.049, f2 = 0.004). Time spent using an instant messaging application was significantly positively associated with positive psychosocial outcomes (ß = 0.068, p = 0.031, f2 = 0.005). The proposed path model had an acceptable model fit. DISCUSSION: Study results indicated that older adults' social media use behaviors were associated with their psychosocial well-being. CONCLUSIONS: Older adults are recommended to use social media for appropriate time periods as an important way to promote social engagement for their psychosocial well-being.

Preferences for end-of-life care: A cross-sectional survey of Chinese frail nursing home residents.

AIM AND OBJECTIVES: To assess (1) the experience, knowledge and preferences of end-of-life care among frail nursing home residents and (2) the preferences of residents' family caregivers. BACKGROUND: Globally, nursing homes are becoming an important place where many older people will receive their end-of-life care. Thus, assessing the end-of-life care preferences among nursing home residents is crucial. DESIGN: Cross-sectional survey. METHODS: Residents aged ≥65 years, with frail or pre-frail status (n = 286) in 34 nursing homes were interviewed using a structured questionnaire. Descriptive statistics were used to describe the outcomes and regression analyses were used to evaluate factors related to the outcomes. Kappa statistics were used to examine the agreement between the preferences among 21 residents and their family caregivers. The manuscript was guided by the STROBE checklist. RESULTS: 5.9% and 10.5% of the participants had heard of advance care planning and advance directive respectively. After explanations of the terms by the research team, 42.3% of the participants preferred advance care planning, whereas 22.0% preferred advance directive. The top reason for not preferring advance care planning/advance directive is perceiving them as 'not necessary'. Nursing homes were the most preferred place to receive end-of-life care (41.6%). Whereas hospitals were the most preferred place for death (36.0%). The agreement among resident and family caregiver dyads ranged from none to minimal in most outcomes. CONCLUSIONS: This study revealed the lack of awareness around advance care planning and advance directive among frail nursing home residents. Future research should focus on developing effective educational interventions to enhance the residents' awareness of these topics. RELEVANCE TO CLINICAL PRACTICE: To increase awareness among nursing home residents, more educational programs should be implemented. Frail older residents might not see the relevance of advance care planning; interventions need to include both current and future care to increase its relevance.

A cross-sectional, observational study of nutritional status and eating behaviours in people living with dementia in acute care settings.

AIMS AND OBJECTIVES: To understand the nutritional status, observing eating difficulties during mealtimes for people living with dementia in acute care settings. BACKGROUND: Changed eating behaviours caused by declining cognitive function is common in people living with dementia which can lead to malnutrition. Malnutrition is associated with prolonged hospitalisation and increased mortality. People living with dementia in acute care settings are at high risk of malnutrition. This highlights the importance of better understanding the nutritional intake and eating behaviours of people living with dementia in acute care settings. DESIGN: This study is a cross-sectional, observational study. METHODS: Data of mealtime difficulties and nutritional status of people living with dementia were collected in four geriatric care wards (in acute or sub-acute hospitals) by using Feeding Difficulty Index and Mini Nutritional Assessment Short-Form. The STROBE checklist was used throughout this study. RESULTS: The study included 94 people living with dementia. The median age of the participants was 85.86 years old, with a Feeding Difficulty Index of 8.27 and had stayed in hospitals for average 14.46 days, with an average total feeding time of 24.61 min. Only 1.2% of participants were considered to be in normal nutritional status, whereas 72.1% were malnourished. All participants required partial or full assistance during mealtime. Participants with higher scores on the Feeding Difficulty Index have longer total feeding times, compared to those with lower scores. CONCLUSIONS: Malnutrition is prevalent in people living with dementia. People living with dementia demonstrate varying mealtime difficulties depending on the level of dependence. Mealtime assistance training programs are warranted and are beneficial for nursing staff and family members to improve their feeding skills and knowledge. NO PATIENT OR PUBLIC CONTRIBUTION: This study did not involve patients, service users, caregivers or members of the public. RELEVANCE TO CLINICAL PRACTICE: The study is relevant to clinical practice by identifying changed eating behaviours or mealtime difficulties in people living with dementia in acute care settings can significantly decrease the risk of malnutrition.

Determinants of the intention to work in aged care: a cross-sectional study to assess gerontological nursing competencies among undergraduate nursing students.

BACKGROUND: There are huge demands for aged-care workers, and undergraduate gerontological nursing education plays a critical role in providing academic and professional training. PURPOSE: To examine relationships of characteristics, aged-care education, and gerontological nursing competencies with the intention to work in aged care. METHODS: An online survey was distributed to undergraduate nursing students between April and June 2022 to gather characteristics, relevant aged-care education, gerontological nursing competencies, and intentions to work in aged care data. Multivariate regression analyses were conducted to identify determinants of the intention to work in aged care. RESULTS: Students (n = 358) who were older (p < 0.001) and who were married (p < 0.001) had higher intentions to work in aged care. "Promoting mental health and psychological well-being", "Providing evidence-based dementia care", and "Enabling access to technology", were also associated with positive intentions. CONCLUSIONS: This study provides evidence on determinants of the intention to work in aged care, particularly gerontological nursing competencies.

Telehealth in palliative care during the COVID-19 pandemic: A systematic mixed studies review.

BACKGROUND: The coronavirus disease-2019 (COVID-19) pandemic caused unprecedented disruption to healthcare delivery worldwide. The use of telehealth practices rapidly expanded during the pandemic, while its application in palliative care remains a conflicted issue. AIMS: The aims of this study were to evaluate users' reports of their satisfaction with telehealth palliative care during COVID-19 and to identify facilitators and barriers to telehealth implementation in palliative care during COVID-19. METHODS: A systematic search of the literature, including studies between January 2020 and June 2022, was conducted using PubMed, MEDLINE, CINAHL Plus, Embase, and Google Scholar. Empirical studies of telehealth in palliative care during COVID-19 were included. RESULTS: A total of 18 studies were included in the review, of which nine were outpatient consultations, four were family meetings, two were remote volunteering programs, two were inpatient care, and one was a residential care home needs assessment. The satisfaction rates were high (66%-99%) among patients and family members who participated in telehealth consultations, but the satisfaction with family meetings was mixed. Compared with their clients, healthcare professionals were less likely to assess telehealth as satisfactory. The authors identified four barriers and four facilitators. The barriers were technological challenges, lack of nonverbal communication, ethical concerns, and limitations for clinical practice. The facilitators were accessibility and convenience, visual cues, facilitation and training, and family engagement. LINKING EVIDENCE TO ACTION: This systematic mixed studies review suggests that current evidence supports the feasibility of telehealth implementation in palliative care for outpatient consultations and routine follow-up appointments. This review also identified facilitators and barriers to telehealth in palliative care, and the findings can inform the implementation of future palliative care services. Future attention should be paid to the effectiveness of telehealth implementation in palliative care patients.

Effectiveness of motivational strategies on physical activity behavior and associated outcomes in patients with cancer: A systematic review and meta-analysis.

BACKGROUND: Motivational interviewing is a client-centered counseling technique widely applied as a behavior change strategy. It has been adopted to help cancer patients modify health behaviors. The effectiveness of motivational interviewing on physical activity behavior and its associated outcomes in cancer patients is unclear. AIM: The aim of this review was to determine the effect of motivational interviewing with other motivational strategies on physical activity behavior and associated outcomes in cancer patients. METHODS: This is a systematic review and meta-analysis of randomized controlled trials, following PRISMA guidelines. Eight English databases were searched from inception to October 2022. The outcomes were evaluated using standardized mean differences (SMDs) with fixed- and random-effects models. Methodological quality of the studies was assessed by Cochrane Risk of Bias Tool 2.0. RESULTS: Eight trials with 450 participants were identified, with sample sizes ranging from 25 to 87. The number of motivational interviewing sessions ranged from one to 12. The types of motivational strategy intervention varied. Apart from motivational interviewing, pedometers were frequently used as a strategy. The quality of the included studies differed, with one out of eight scoring low in the overall risk of bias. Our meta-analysis indicated that motivational interviewing with other motivational strategies significantly promoted the total physical activity level (SMD = 0.34, 95% confidence interval [0.10, 0.58], p = .005; low certainty), but not did not affect other physical and psychosocial outcomes. CONCLUSION: The combination of motivational interviewing with other motivational strategies was beneficial in increasing the total physical activity level of cancer patients. LINKING EVIDENCE TO ACTION: Motivational interviewing can be a clinical communication skill that healthcare professionals, especially nurses, can acquire to motivate patients to change their behaviors to promote health. Future studies adopting motivational interviewing interventions could consider additional motivational strategies, such as pedometers, to maximize the benefits on physical activity behaviors.

Effectiveness of auricular acupoint therapy targeting menstrual pain for primary dysmenorrhea: A systematic review and meta-analysis of randomized controlled trials.

BACKGROUND: Primary dysmenorrhea (PD) is a global public health concern affecting women's health and quality of life, leading to productivity loss and increased medical expenses. As a non-pharmacological intervention, auricular acupoint therapy (AAT) has been increasingly applied to treat PD, but the overall effectiveness remains unclear. AIMS: The aim of this review was to synthesize the effects of AAT targeting menstrual pain among females with PD. METHODS: Eight databases (PubMed, EMBASE, AMED, CINAHL Plus, Cochrane Library, Web of Science, China National Knowledge Infrastructure and Wanfang Data) and three registries (ClinicalTrials.gov, ISRCTN Registry and the Chinese Clinical Trial Registry) were searched to identify existing randomized controlled trials (RCTs) from inception to 21 August 2022. Two reviewers independently screened, extracted the data, and appraised the methodological quality and the evidence strength using the Cochrane risk-of-bias tool for randomized trials (RoB 2) and the GRADE approach. RESULTS: A total of 793 participants from 11 RCTs were included. Despite substantial heterogeneity, AAT was more effective in reducing menstrual pain and related symptoms than placebo and nonsteroidal anti-inflammatory medications (NSAIDs). No significant subgroup differences were found between study locations as well as invasiveness, duration, type, acupoints number, ear selection and provider of AAT. Only minor adverse effects of AAT were reported. LINKING EVIDENCE TO ACTION: AAT can help women with PD, particularly those who are refrained from pharmaceuticals. Primary healthcare professionals, including nurses, can be well-equipped to provide evidence-based and effective AAT for people with PD. AAT can be used in a broader global clinical community. To provide an optimal effect and have wider usability, a unified practice standard is required, which would necessitate further adaptation of clinical care of people with PD. AAT effectively decreased menstrual pain and other accompanying symptoms of PD. More research is needed to identify effective AAT features and explore optimal therapy regimes for PD.

Incidence of postoperative delirium in older adults undergoing surgical procedures: A systematic literature review and meta-analysis.

BACKGROUND: With the increase in life expectancy around the globe, the incidence of postoperative delirium (POD) among older people (≥65 years) is growing. Previous studies showed a wide variation in the incidence of POD, from 4% to 53%, with a lack of specific evidence about the incidence of POD by specific surgery type among older people. The aim of this systematic review and meta-analysis was to determine the incidence of POD by surgery type within populations 65 years and over. METHODS: Databases including PubMed, Cochrane library, Embase, and CINAHL were searched until October 2020. Due to the relatively higher number of meta-analyses undertaken in this area of research, a streamlined systematic meta-analysis was proposed. RESULTS: A total of 28 meta-analyses (comprising 284 individual studies) were reviewed. Data from relevant individual studies (n = 90) were extracted and included in the current study. Studies were grouped into eight surgery types and the incidence of POD for orthopedic, vascular, spinal, cardiac, colorectal, abdominal, urologic, and mixed surgeries was 20%, 14%, 13%, 32%, 14%, 30%, 10%, and 26%, respectively. POD detection instruments were different across the studies, with Confusion Assessment Method (CAM & CAM-ICU) being the most frequently adopted. LINKING EVIDENCE TO ACTION: This study showed that POD incidence in older people undergoing surgery varied widely across surgery type. The more complex surgeries like cardiac and abdominal surgeries were associated with a higher risk of POD. This highlights the need to include the level of surgery complexity as a risk factor in preoperative assessments.

Factors associated with perceived cognitive impairment in patients with advanced lung cancer: a cross-sectional analysis.

PURPOSE: Perceived cognitive impairment refers to cognitive dysfunction that particularly involves impairment in working or short-term memory, and inattention. This study aimed to identify factors associated with perceived cognitive impairment in patients with advanced lung cancer. METHODS: This cross-sectional analysis used pooled data from a prospective, ongoing randomized controlled trial examining the effectiveness of exercise in patients with advanced lung cancer (Trial Registration: NCT04119778). Patients diagnosed with stage IIIB or IV non-small cell lung cancer were recruited from three public hospitals in Hong Kong between December 2018 and December 2021. Demographics, daily step count, sleep quality, fatigue, depression, anxiety, and perceived cognitive impairment were included in the analyses. Multivariate logistic regression analysis was used to determine the most critical risk factors associated with perceived cognitive impairments in attention and memory. RESULTS: A total of 226 patients were included and analyzed, 35.4% of patients had perceived attention impairment and 58.4% had perceived memory impairment. The daily step count (adjusted odds ratio [aOR] = 0.496; confidence interval [CI] = 0.258-0.954), fatigue (aOR = 1.342; CI = 1.903-1.648), and anxiety (aOR = 1.179; CI = 1.042-1.335) were associated with a significantly increased risk of perceived attention impairment, while anxiety (aOR = 1.126; CI = 1.008-1.257) was identified as the most significant factor for perceived memory impairment. CONCLUSION: The findings of this study can inform the design of effective interventions to reduce perceived cognitive impairment and promote the quality of life and well-being of patients with advanced lung cancer.

The relationship between physical activity trajectories and frailty: a 20-year prospective cohort among community-dwelling older people.

BACKGROUND: Studies on examining the relationship between physical activity patterns and frailty are lacking. This study examined physical activity patterns in older people and investigated the relationship between physical activity and frailty as well as identifying the predictors of frailty. METHODS: We used a nationally representative longitudinal database, the Taiwan Longitudinal Study of Aging (TLSA) database, and data for a 20-year period were extracted and analyzed. A total of 5131 participants aged ≥ 60 years in 1996 were included in the current analysis. Information regarding demographic characteristics, frailty, physical activity, comorbidities, oral health, and depressive symptoms was extracted from the TLSA database. Physical activity patterns were examined using group-based trajectory modeling from 1996 to 2015. Potential predictors were examined by performing multivariate logistic regression. RESULTS: Four trajectories of the physical activity pattern were found: consistently physically inactive (33.7%), consistently physically active (21.5%), incline (21.6%), and decline (23.2%). Throughout the period, the trajectories of the four groups significantly differed from each other at year 2015, with the incline and decline groups exhibiting the lowest and highest frailty scores, respectively (p < 0.001). Older age, male, poor oral health, diabetes, chronic kidney disease, and depressive symptoms were identified as risk factors for frailty. CONCLUSION: Physical activity reduces the risk of chronic conditions, which contributes to healthy longevity. This study can guide the development of future research and interventions to manage frailty in older people, particularly in considering previous physical activity trajectories within the life course.

Using the nursing delirium screening scale in assessing postoperative delirium: A meta-regression.

The nursing delirium screening scale (Nu-DESC) was developed for the rapid assessment of delirium, but little is known regarding the performance of the Nu-DESC in assessing postoperative delirium. The purpose of this systematic review and meta-analysis was to review and summarize the evidence of the diagnostic accuracy of the Nu-DESC in assessing postoperative delirium. The EMBASE, MEDLINE, Cochrane Library, CINAHL, and a Chinese e-Journal database were searched from the period of the inception of the Nu-DESC to June 18, 2020. Participants were adult (age ≥ 18 years) postoperative patients who received any type of surgery and any method of anesthesia. The quality assessment of diagnostic accuracy studies-2 was employed to assess the risk of bias among the selected studies, and meta-regression analyses were used to detect sources of between-study heterogeneity. Eleven studies involving 2062 postoperative patients in surgical settings were included. The Nu-DESC revealed a pooled sensitivity of 0.73 (95% confidence interval, 0.44-0.90) and a specificity of 0.93 (0.87-0.96). The area under the summary receiver operating characteristics curve was 0.94 (0.91-0.96), which also confirmed the accuracy of the Nu-DESC. Covariates, including the region of study and the standard reference used, were identified as possible sources of heterogeneity in the meta-regression. The findings of this review can update existing clinical guidelines for postoperative delirium. On the basis of its satisfactory diagnostic performance, we suggest that the Nu-DESC could be considered for nurses and allied health professionals for assessing postoperative delirium. However, because of the heterogeneity, the result of this meta-analysis should be considered with caution.

Nurse visit utilization and blood pressure control: A multi-cohort study in New Zealand.

OBJECTIVE: This study aimed to retrospectively examine the contribution of nurses to population health outcomes with reference to nurse visits and blood pressure measurement in primary health settings. DESIGN: A retrospective study was conducted using New Zealand Health Survey (NZHS) from 2012 to 2017. SAMPLE: Adult population who are 18 years old and over living in New Zealand. MEASUREMENTS: Age, gender, and ethnicity, the service utilization of primary health care nurse visit and blood pressure measurement were extracted from the NZHS (2012-2017) to compare with the service utilization of primary health care nurses by different demographic groups. RESULTS: Females who have treated hypertension shows higher utilization of nurse visit than males. From 2015 to 2017, the participants in this cohort have visited a primary health care nurse at least more than once within a year. With blood pressure control, the overall pooled results show the impact of visiting primary health nurses on systolic and diastolic blood pressure control. CONCLUSION: Our study at a national scale, demonstrated the impact of nurse's contribution to population health outcomes among people living with hypertension in New Zealand. Nurses are key to improving population health outcomes and to achieve universal health coverage.

Critical care nurses' knowledge and attitudes and their perspectives toward promoting advance directives and end-of-life care.

BACKGROUND: End-of-life care can be a difficult and challenging process for critical care nurses in intensive care units (ICUs) due to the care plan shifts from providing life-sustaining measures to end-of-life care. The aims of this study were to assess critical care nurses' perceived knowledge and attitudes toward end-of-life care, as well as their perspectives on promoting advance directives and the associated factors. METHODS: A cross-sectional study was undertaken in an acute major metropolitan medical center in northern Taiwan between February and March 2020, and 250 critical care nurses were invited to participate in the study. Data on demographics, self-perceived knowledge of end-of-life care, attitudes toward end-of-life care, and perspectives of promoting advance directives were collected. A multiple linear regression model with stepwise selection was used to identify factors associated with their perspectives of promoting advance directives. RESULTS: The law related to end-of-life care was rated as the least familiar part of the self-perceived end-of-life care knowledge, while 'I have sufficient knowledge to care for patients who have accepted end-of-life care' was the lowest level of agreement in attitude scores among critical care nurses. Increased levels of perceived knowledge (ß = 0.134; p = 0.045) and attitudes (ß = 0.423; p < 0.001) toward end-of-life care were associated with the perspectives of promoting advance directives. Nurses who worked in cardiac (ß = -0.234; p < 0.001) and respiratory ICUs (ß = -0.135; p = 0.024) had less motivation to promote advance directives (F = 16.943; p < 0.001). CONCLUSION: Given their important contributions to ICU care services, appropriate and meaningful support is required to optimize critical care nurses' involvement in end-of-life care. This study demonstrated a significant impact on perspectives of promoting advance directives of critical care nurse participants. Findings from this study can inform the design of effective nurse support programs to enhance the promotion of advance directives in intensive care settings.

The COVID-19 pandemic: Narratives of front-line nurses from Wuhan, China.

This study aimed to explore the experiences of nurses in Wuhan Hospital as front-line workers during the COVID-19 pandemic. A descriptive qualitative study of such nurses was conducted from a tertiary hospital in Wuhan. Semi-structured individual interviews were undertaken with 8 registered nurses who were front-line health workers in one of the COVID-19 wards and 3 nursing managers from the response team. Five discrete themes were identified from the narratives of nurses' experiences during the COVID-19 outbreak in Wuhan: "content of fundamental care," "teamwork," "reciprocity," "nurses' own worries," and "lifelong learning and insights." Nurses in the front line of care during the COVID-19 pandemic can contribute important information from their hands-on experience for providing a holistic response to an infectious outbreak like COVID-19. The concerns nurses raised at both personal and professional levels have implications for nursing education and clinical practice settings, particularly in the time of a pandemic when nurses' well-being requires attention, and at the same time for considering organizational factors that enable nurses to provide care to patients with confidence. Hospital policies and nursing management need to be ready and adhere to flexible work planning systems and approaches during a pandemic.
